Skyrails is an interactive graph visualization system that looks a lot like a video game. Explore relationships, visit nodes, and immerse yourself in the data. As I watch the demo video on YouTube, I feel like I'm seeing another world.
You've got the standard ball and stick view. Whether it's useful for analysis or deeper understanding of relationships between whatever is up for debate, but one thing's for sure â€“ it looks cool. Plus the code is open source.
